sounds like lack of fuel, clogged filter, carb gummed up from crappy fuel. Can you take carb bowl off and spray carb cleaner through needle. Remove float, just dont lose the little pin that holds float in place

I just put my small chain saw in the shop because of ethanol. One day it would not hit but half a lick and when I let off the throttle, it died and would not fire again. Don't let that stuff sit for more than a couple of months.

I'm a small engine mechanic. Gasohol draws moisture like a paper towel. never leave it in your engine more than a week without running it for at least 30 min. because it made from corn it also molds! It will turn the inside of the carburetor green and plug every hole in it. use green stabil with the gas. never buy more gasohol than you can use in a day. when you finish use your equipment run it dry and spray seafoam in the carb and cylinder. do this and your equipment will last.
